Content: 98-100% LLDPE resin
Additives: May contain trace amounts of slip agents, antioxidants, anti-block agents (typically less than 2%)
Impurities: No hazardous impurities at concentrations relevant to normal use
Inhalation: Move affected person to fresh air if exposure to fumes during processing causes discomfort, seek medical attention for continued symptoms
Skin Contact: If hot molten material contacts skin, cool rapidly with water, do not attempt to remove solidified polymer, seek medical help
Eye Contact: Flush with clean water for several minutes if dust or particles get into eyes, see a doctor if irritation persists
Ingestion: Swallowing is unlikely due to product form (pellets/granules), if swallowed, rinse mouth, seek medical advice if discomfort occurs
Notes for Doctors: Treat based on symptoms, no specific antidote exists
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Avoid high-pressure water jet which may spread burning pellets
Specific Hazards: Emits dense black smoke, carbon monoxide, carbon dioxide, possibly acrolein and other toxic gases
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing to avoid exposure to toxic smoke
Special Precautions: Cool containers threatened by fire with water spray
Explosion Risk: Fine dust generated during handling can form explosive mixtures with air
Personal Precautions: Avoid creating dust, use appropriate PPE such as gloves and goggles
Environmental Precautions: Prevent pellets from entering soil, waterways, or drains
Methods for Cleaning Up: Sweep up pellets, place in suitable containers for recycling or disposal, avoid wet sweeping as pellets may become slippery
Additional Advice: Disposal in accordance with local environmental regulations
Precautions for Safe Handling: Minimize dust generation, clean spills quickly, maintain good industrial hygiene, use proper lifting techniques for large bags
Safe Storage Conditions: Store in a cool, dry, well-ventilated space, avoid direct sunlight and sources of ignition
Incompatibilities: Strong oxidizing agents may degrade material
Packaging Materials: Store in original packaging or suitable sealed containers to prevent contamination
Other Storage Instructions: Avoid stacking bags or containers too high to prevent collapse and potential physical injury
Engineering Controls: Use local exhaust ventilation at points of dust generation or thermal processing
Occupational Exposure Limits: No specific TLV for LLDPE; monitor for dust levels and thermal degradation products
Personal Protective Equipment:
— Respiratory Protection: Dust mask if ventilation is inadequate or during high dust generation
— Eye Protection: Safety goggles to prevent dust particles from entering eyes
— Skin Protection: Protective gloves and long sleeves when handling hot molten polymer or bulk materials
Additional Recommendations: Provide wash stations and eye-wash facilities in work areas
Appearance: Translucent to opaque, tough pellets or granules
Color: White or natural
Odor: Odorless or faint hydrocarbon-like
Melting Point: 110–130°C
Boiling Point: Not applicable
Density: 0.915–0.935 g/cm³
Solubility in Water: Insoluble
Vapor Pressure: Negligible at room temperature
Flash Point: >300°C
Auto-Ignition Temperature: 340–380°C
Other Information: Stable under normal conditions, degrades with prolonged exposure to sunlight (UV radiation) unless stabilizers are added
Chemical Stability: Stable during storage and use if kept under proper conditions
Reactivity: Not reactive under normal handling and storage
Conditions to Avoid: Excessive heat, open flames, prolonged exposure to direct sunlight, strong oxidizers
Incompatible Materials: Strong oxidizing agents such as peroxides, nitric acid may attack polymer
Hazardous Decomposition Products: Burning or thermal degradation produces carbon oxides, aldehydes, and other hydrocarbon fumes
Polymerization: Hazardous polymerization does not occur
Acute Toxicity: No known acute toxicity by ingestion, inhalation, or skin exposure
Chronic Effects: Not expected to cause chronic health problems under normal industrial or commercial use
Skin Contact: No irritation expected from solid form; hot or molten material may cause burns
Eye Contact: Dust may cause mild mechanical irritation
Inhalation: Dust or fumes may cause mild respiratory discomfort, especially during processing
Other Effects: No evidence of carcinogenic, mutagenic, or reproductive toxicity, as per available data
Environmental Impact: LLDPE is not readily biodegradable; persistence in soil and water leads to physical hazards for wildlife through ingestion or entanglement
Aquatic Toxicity: Low toxicity to aquatic life, but physical presence poses a threat to fish and birds
Mobility: Pellets may be transported by wind or water over long distances
Bioaccumulation: Does not bioaccumulate chemically, but microplastics risk exists in the food chain
Degradability: Breaks down slowly under UV light, but not mineralized in the environment for decades
Recommendations: Implement best practices for pellet loss prevention during transport, storage, and use
Waste Handling: Collect and recycle clean uncontaminated product wherever possible; contaminated material should go to landfill or incineration as per local regulation
Prohibited Disposal: Do not discharge pellets into watercourses or natural soil
Recycling: Mechanical or chemical recycling is possible for many LLDPE grades
Incineration: Permitted with suitable controls in approved facilities, as combustion produces mostly carbon dioxide and water
Disposal Containers: Use appropriate, labeled sacks or containers to avoid environmental contamination
Recommendations: Consult local waste authority regarding proper procedures for specific situations
UN Number: Not regulated as a hazardous material for transport
Proper Shipping Name: Linear Low-Density Polyethylene
Class: Not classified as dangerous goods under ADR, RID, IMDG, or IATA
Packaging: Use secure, weather-resistant packaging to avoid dispersal of pellets
Other Transport Requirements: Prevent package rupture, label shipments to raise awareness of plastic pellet spill risks
Environmental Hazards: Pellet spills during transport can lead to widespread environmental pollution; shippers must take preventive measures

OSHA Regulations: Not controlled under OSHA Hazard Communication Standard for hazardous chemicals
SARA Title III: Not listed as an extremely hazardous substance or toxic chemical
Other National Regulations: Compliance required with country-specific chemical control laws
Labeling Requirements: No labeling required for hazardous substance, but good practice suggests clear, descriptive labeling for all chemical shipments
